BACKGROUND

Since the widespread introduction of antibiotics in the 1940s, the same storyline has repeated itself over and over again: new antibiotic is introduced and then resistant variants emerge and quickly spread, effectively limiting the utility and lifespan of the drug. Staphylococci are frequently the cause of hospital infections such as infections from implanted medical devices. Many staphylococcal strains have become resistant to many modern day antibiotics. Improved therapies are needed.

One proposed strategy to overcome the problem of highly virulent and resistant variants is to indirectly attack bacteria by interfering with their means of communication, also known as quorum sensing. Targeting microbial communication makes sense because bacteria coordinate many of their virulence and pathogenesis pathways through these systems. Quave et al., report quorum sensing inhibitors of Staphylococcus aureus from botanical extracts. Planta Med. 2011, 77(02):188-95. See also Quave & Horswill, Front Microbiol, 2014, 5:706.

Schinus terebinthifolia Raddi (synonym: Schinus terebinthfolius) is a flowering plant in the family Anacardiaceae, which can be found in Brazil, the Caribbean and across the southern United States. It is considered an invasive species in a number of countries.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 illustrates the regulation of S. aureus pathogenesis with quorum sensing. S. aureus produces an extensive array of enzymes, hemolysins, and toxins that are essential to its ability to spread through tissues and cause disease. These virulence factors serve a wide scope of purposes in the infection process, including disruption of the epithelial barrier, inhibition of opsonization by antibody and complement, neutrophil cytolysis, interference with neutrophil chemotaxis, and inactivation of antimicrobial peptides. The expression of these invasive factors is controlled by cell-density quorum sensing using the autoinducing peptide (AIP) molecule. Like other quorum sensing signals, AIP accumulates outside the cell until it reaches a critical concentration and then binds to a surface receptor called AgrC, initiating a regulatory cascade. Since AIP controls the expression of accessory factors for S. aureus, this regulatory system has been named the accessory gene regulator (agr), and the majority of the proteins necessary for this quorum-sensing system to function are encoded in the agr chromosomal locus.

FIG. 2A shows a description of extracts and fractionation scheme for fruits (430 series). Fruits of Schinus terebinthifolia were harvested at maturity from wild populations in DeSoto County, Fla. Percent yield from dry plant material is shown for each extract and fraction. The bioassay-guided fractionation scheme is illustrated, demonstrating the path from crude fruit extract to refined bioactive fraction 430D-F5. Percent yields of extracts in relation to starting dry plant material are represented at each separation step. The most active fractions at each step are highlighted in bold.

FIG. 2B shows the corresponding HPLC chromatograms for the most active fractions which demonstrate an increase in relative abundance of peaks at a retention time range of 45-50 min.

FIG. 3A shows data indicating 430D-F5 inhibits agr activity for all four alleles in a non-biocide manner. Data are represented as percent agr activity or growth of the vehicle (DMSO) control at 24 hours. The solid lines represent agr activity, measured by fluorescence, and the dashed lines represent growth, measured using OD600.

FIG. 3B shows a table of MIC₅₀ and MIC₉₀ data for each agr allele.

FIG. 4 shows data indicating 430D-F5 inhibits δ-toxin and α-hemolysin production a dose-dependent manner. Levels of δ-toxin were quantified by HPLC analysis of culture supernatant following treatment with sub-MIC50 concentrations of 430D-F5. S. epidermidis strain is NRS 101, all others S. aureus. Results are expressed as the peak area, normalized for optical density (600 nm) at the time of supernatant harvest.

FIG. 5 shows data indicating toxicity of S. aureus supernatants to HaCaTs. An immortalized line of human keratinocytes was treated with supernatants of S. aureus (NRS385) that was grown +/−430D-F5 or vehicle (DMSO). LDH assay demonstrates that treated cultures lacked the suite of exotoxins in their supernatants, and thus did not impact HaCaT viability.

FIG. 6 shows data on the impact of 430D-F5 on S. aureus biofilm formation and planktonic growth in a biofilm model with crystal violet stained biofilm in 96-well plates. The optical density (OD595 nm) of the crystal violet eluent is plotted against the OD600 nm for planktonic cells, measured by transfer of the well supernatants to a new 96-well plate.

FIG. 7A shows data indicating 430D-F5 attenuates MRSA-induced dermatopathology in a murine model of skin and soft tissue infection. BALB/c mice were intradermally injected with 1×108 CFUs of LAC (USA 300 isolate, AH1263). Mice received a single dose of 430D-F5 (at 50 μg) or the vehicle control (DMSO) at the time of infection. 430D-F5 attenuates dermatopathology with a single dose of 50 μg.

FIG. 7B shows data indicating 430D-F5 mediates quorum quenching in vivo. To determine if 430D-F5 inhibits quorum sensing in vivo, mice were challenged intradermally with an agr P3-lux reporter strain (AH2759)+/−430D-F5 and agr-driven bioluminescence was measured at the indicated time points via IVIS imaging. Quorum sensing peaks at 3 hours post injection, and a single injection of 430D-F5 exhibits significantly significant inhibition of the system for the first 4 h post-injection.

FIG. 8A shows HPLC-DAD chromatogram of 430D-F5 and MS (ESI) positive ion mode and negative ion mode.

DETAILED DISCUSSION

Before the present disclosure is described in greater detail, it is to be understood that this disclosure is not limited to particular embodiments described, and as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting, since the scope of the present disclosure will be limited only by the appended claims.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present disclosure, the preferred methods and materials are now described.

All publications and patents cited in this specification are herein incorporated by reference as if each individual publication or patent were specifically and individually indicated to be incorporated by reference and are incorporated herein by reference to disclose and describe the methods and/or materials in connection with which the publications are cited. The citation of any publication is for its disclosure prior to the filing date and should not be construed as an admission that the present disclosure is not entitled to antedate such publication by virtue of prior disclosure. Further, the dates of publication provided could be different from the actual publication dates that may need to be independently confirmed.

As will be apparent to those of skill in the art upon reading this disclosure, each of the individual embodiments described and illustrated herein has discrete components and features which may be readily separated from or combined with the features of any of the other several embodiments without departing from the scope or spirit of the present disclosure. Any recited method can be carried out in the order of events recited or in any other order that is logically possible.

Embodiments of the present disclosure will employ, unless otherwise indicated, techniques of medicine, organic chemistry, biochemistry, molecular biology, pharmacology, and the like, which are within the skill of the art. Such techniques are explained fully in the literature.

It must be noted that, as used in the specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. In this specification and in the claims that follow, reference will be made to a number of terms that shall be defined to have the following meanings unless a contrary intention is apparent.

As used herein, the term “combination with” when used to describe administration with an additional treatment means that the agent may be administered prior to, together with, or after the additional treatment, or a combination thereof.

As used herein, “subject” refers to any animal, preferably a human patient, livestock, or domestic pet.

As used herein, the terms “prevent” and “preventing” include the prevention of the recurrence, spread or onset. It is not intended that the present disclosure be limited to complete prevention. In some embodiments, the onset is delayed, or the severity is reduced.

As used herein, the terms “treat” and “treating” are not limited to the case where the subject (e.g. patient) is cured and the disease is eradicated. Rather, embodiments of the present disclosure also contemplate treatment that merely reduces symptoms, and/or delays disease progression.

As used herein, “relative abundance” refers to amount determined from electrospray ionization mass spectrometry. Mass spectrometry is an analytical technique that can provide both qualitative (structure) and quantitative (molecular mass or concentration) information on analyte molecules after their conversion to ions. The molecules of interest are first introduced into the ionization source of the mass spectrometer, where they are first ionized to acquire positive or negative charges. The ions then travel through the mass analyzer and arrive at different parts of the detector according to their mass to charge (m/z) ratio. After the ions make contact with the detector, useable signals are generated and recorded by a computer system. The computer displays the signals graphically as a mass spectrum showing the relative abundance of the signals according to their m/z ratio.

Extracts Exhibit Quorum Quenching Activity

To test the anti-infective properties of Schinus terebinthifolia, a suite of bioactive compounds was identified in S. terebinthifolia fruits that are able to inhibit the agr system in Staphylococcus aureus without killing or inhibiting growth. As the global regulator of virulence in S. aureus, the agr system is responsible for initial infection of host cells, evasion of the host immune system, quorum sensing, and the destruction of tissues with toxins and other enzymes. Through inhibition of the agr system with the use of small molecule inhibitors isolated from S. aureus virulence could be decreased, thus limiting the severity of disease and increasing efficacy of existing antibiotics.

One main concern and point of debate in the literature concerning the utility and limitations of anti-virulence drugs to treat S. aureus infection is the potential for activation of other virulence pathways, such as biofilm formation. Here, studies indicate while at lower concentrations (2-16 μg mL⁻¹) there was an increase in biofilm formation, there was also an abrupt drop in attached biofilm observed at 32 μg mL⁻¹, exhibiting a phenotype similar to that of the AsarA control (FIG. 6). This suggests that at doses required for quorum quenching activity, biofilm formation will also be inhibited.

In vivo assessment of the most active fraction (430D-F5) demonstrated inhibition of the severity of necrosis at an infection site. Furthermore, a model of real time in vivo tracking of agr activity was applied to monitor drug activity. It is contemplates that 430D-F5 and isolated small molecules are useful in preventing or treating established infections both alone and in combination with another antibiotic or combination antibiotic therapy.

Fluorescent reporter strains were used to identify fractions of 430D (the butanol partition of S. terebinthifolia fruits) that exhibit quorum quenching activity. The S. terebinthifolia fruit extracts (430, 430D, 430D-F5) inhibit the hemolytic capacity of S. aureus isolates. Fraction (430D-F5) was the most potent. To confirm that the agr-quenching activity observed with reporters also leads to quenching of exotoxin production, levels of δ-toxin were quantified in the bacterial supernatant. One major benefit of using virulence inhibitors with current extracts or one or more compounds therein with a classical antibiotic is the potential for increased antibiotic efficacy. By blocking the toxins responsible for immune response damage, the antibiotics and immune system can work more in concert to eliminate the bacteria.

In certain embodiments, the extract comprises a mixture of compounds having at least one component from each of the following groups a) to d): a) a compound having a molecular formula of C₃₀H₁₇O₁₀; b) a compound having a molecular formula of C₃₀H₂₁O₁₀; c) a compound having a molecular formula of C₃₀H₄₅O₄; and d) a compound having a molecular formula of C₃₀H₄₅O₄.

In certain embodiments, the extracting process comprises the step of mixing the fruit from the plant with a polar solvent, such as a liquid comprising methanol, ethanol, ethyl acetate, n-butanol, acetonitrile, acetone, methylene chloride or chloroform, under conditions such that a mixture of compounds in the fruit dissolves in the solvent. In certain embodiments, the process further comprises the step of removing the solvent by evaporation from the mixture of compounds. In certain embodiments, the process further comprises the step of purifying the mixture of compounds by liquid chromatography through a solid absorbent, e.g., wherein the solid absorbent comprises silica gel or alumina.

In certain embodiments, the disclosure relates to extracts comprising a fruit derived mixture of compounds from a Schinus plant wherein the extracting process comprises the steps of: mixing a fruit with methanol under conditions such that fruit compounds dissolves in the methanol and removing the methanol providing a methanol derived mixture of compounds; partitioning the methanol derived mixture of compounds with hexane and water providing a water derived mixture of compounds; partitioning the water derived mixture of compounds with ethyl acetate and water providing a second water derived mixture of compounds; partitioning the second water derived mixture of compounds by mixing the water with n-butanol under conditions such that fruit compounds dissolve in the butanol and removing the n-butanol providing an n-butanol derived mixture of compounds; and purifying the n-butanol derived mixture of compounds by liquid chromatography.

Chromatography refers to the separation of a mixture of compounds dissolved in a fluid called the mobile phase, which carries the compounds through a structure holding another material called the stationary phase. The various compounds or components of the mixture travel at different speeds, causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a partition coefficient of each compound result in differential retention on the stationary phase and thus changing the separation.

In normal-phase chromatography, the stationary phase is polar. In reversed phase, the stationary phase is nonpolar. Typical stationary phases for normal-phase chromatography are silica or organic moieties with cyano and amino functional groups. For reversed phase, alkyl hydrocarbons are the preferred stationary phase. Examples are solid supports containing a surface conjugated with a hydrocarbon chain, e.g., octadecyl (C18), octyl (C8), and butyl (C4).

In normal-phase chromatography, the least polar compounds elute first and the most polar compounds elute last. The mobile phase typically consists of a nonpolar solvent such as hexane or heptane mixed with a slightly more polar solvent such as isopropanol, ethyl acetate, n-butanol, or chloroform. Retention to the stationary phase decreases as the amount of polar solvent in the mobile phase increases. In reversed phase chromatography, the most polar compounds elute first with the most nonpolar compounds eluting last. The mobile phase is generally a binary mixture of water and a miscible polar organic solvent like methanol, acetonitrile or THF.

In certain embodiments, methods of extraction comprise mixing the fruit of a Schinus plant with an water miscible carbon containing solvent, e.g., such as a protic solvent, an alcohol, methanol, ethanol, 1-propanol, 2-propanol, tetrahydrofuran, acetone, acetic acid, 1,4-dioxane or mixture providing a concentrate with a mixture of compounds and substantially removing the solvent from the concentrate, purifying the solvent derived concentrate to less than 5%, 1%, or 0.5% by weight of the solvent used in the extraction, e.g., evaporating the protic solvent and/or optionally in combination with mixing the concentrate with water, sonicating the water, freezing the water to provide ice, and removing the ice by sublimation (e.g. in a vacuum of low pressure) wherein said purification methods may be repeated in combination. In certain embodiments, the method further comprises suspending the solvent derived concentrate in water and optionally extract impurities in a hydrocarbon solvent such as cyclohexane, heptane, hexane, pentane, 2,2,4-trimethylpentane, separating the hydrocarbon from the water providing a water layer. In certain embodiments, the method further comprises mixing the water layer with a solvent that is immiscible in water (polar and/or aprotic), e.g., such as ethyl acetate, diethyl ether, methyl tertbutyl ether, n-butanol, toluene, methylene chloride, carbon tetrachloride, 1,2-dichloroethant, and/or chloroform, and purifying the solvent to provide a second solvent derived concentrate. In further embodiments, the second derived concentrate is purified one or more times by liquid chromatography, e.g., normal phase chromatography.

Application of the enteric coating to composition can be accomplished by any method known in the art for applying enteric coatings. For example, but not by way of limitation, the enteric polymers can be applied using organic solvent based solutions containing from 5 to 10% w/w polymer for spray applications and up to 30% w/w polymer for pan coatings. Solvents that are commonly in use include, but are not limited to, acetone, acetone/ethyl acetate mixtures, methylene chloride/methanol mixtures, and tertiary mixtures containing these solvents. Some enteric polymers, such as methacrylic acid-methacrylic acid ester copolymers can be applied using water as a dispersant.

Furthermore, plasticizers can be added to the enteric coating to prevent cracking of the coating film. Suitable plasticizers include the low molecular weight phthalate esters, such as diethyl phthalate, acetylated monoglycerides, triethyl citrate, polyethyl glycoltributyl citrate and triacetin. Generally, plasticizers are added at a concentration of 10% by weight of enteric coating polymer weight. Other additives such as emulsifiers, for example detergents and simethicone, and powders, for example talc, may be added to the coating to improve the strength and smoothness of the coating. Additionally, pigments may be added to the coating to add color to the pharmaceutical formulation.

Furthermore, zwitterionic surfactants can be used as emulsifiers. The term “zwitterionic surfactants” refers to those surface-active compounds that carry at least one quaternary ammonium group and at least one carboxylate and one sulfonate group in the molecule. Particularly suitable zwitterionic surfactants are the betaines, such as N-alkyl-N,N-dimethylammonium glycinates, for example cocoalkyldimethylammonium glycinate, N-acylaminopropyl-N,N-dimethylammonium glycinates, for example cocoacyl-amino-propyldimethylammonium glycinate, and 2-alkyl-3-carboxymethyl-3-hydroxyethylimidazolines having in each case 8 to 18 carbon atoms in the alkyl or acyl group, and cocoacylamino-ethylhydroxyethyl-carboxymethyl glycinate. Particular preference is given to the fatty acid amide derivative known under the CTFA name Cocamidopropyl Betaine. Likewise suitable emulsifiers are ampholytic surfactants. The term “ampholytic surfactants” means those surface-active compounds that, apart from a C_(8/18)-alkyl or -acyl group in the molecule, contain at least one free amino group and at least one —CO₂H or —SO₃H group and are capable of forming internal salts. Examples of suitable ampholytic surfactants are N-alkylglycines, N-alkylpropionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropylglycines, N-alkyl-taurines, N-alkylsarcosines, 2-alkylaminopropionic acids and alkylaminoacetic acids having in each case about 8 to 18 carbon atoms in the alkyl group. Particularly preferred ampholytic surfactants are N-cocoalkyl aminopropionate, cocoacyl-aminoethyl aminopropionate and C_(12/18)-acylsarcosine. Finally, cationic surfactants are also suitable emulsifiers, those of the ester quat type, preferably methyl-quaternized difatty acid triethanolamine ester salts, being particularly preferred.

Fats and waxes that can be used are described in the following text. Typical examples of fats are glycerides, i.e. solid or liquid vegetable or animal products which consist essentially of mixed glycerol esters of higher fatty acids, suitable waxes are inter alia natural waxes, for example candelilla wax, carnauba wax, japan wax, esparto grass wax, cork wax, guaruma wax, rice germ oil wax, sugarcane wax, ouricury wax, montan wax, beeswax, shellac wax, spermaceti, lanolin (wool wax), uropygial grease, ceresin, ozokerite (earth wax), petrolatum, paraffin waxes, microcrystalline waxes; chemically modified waxes (hard waxes), for example montan ester waxes, sasol waxes, hydrogenated jojoba waxes, and synthetic waxes, for example polyalkylene waxes and polyethylene glycol waxes. In addition to the fats, suitable additives are also fat-like substances, such as lecithins and phospholipids.

The term “lecithins” is understood by the person skilled in the art as meaning those glycerophospholipids which form from fatty acids, glycerol, phosphoric acid and choline by esterification. Lecithins are thus frequently also known as phosphatidylcholines (PC). Examples of natural lecithins which may be mentioned are the cephalins, which are also referred to as phosphatidic acids and represent derivatives of 1,2-diacyl-sn-glycerol-3-phosphoric acids. By contrast, phospholipids are usually understood as meaning mono- and, preferably, diesters of phosphoric acid with glycerol (glycerophosphates), which are generally considered to be fats. In addition, sphingosines and sphingolipids are also suitable.

Examples of suitable pearlescent waxes are: alkylene glycol esters, specifically ethylene glycol distearate; fatty acid alkanolamides, specifically coconut fatty acid diethanolamide; partial glycerides, specifically stearic acid monoglyceride; esters of polybasic, optionally hydroxy-substituted carboxylic acids with fatty alcohols having 6 to 22 carbon atoms, specifically long-chain esters of tartaric acid; fatty substances, for example fatty alcohols, fatty ketones, fatty aldehydes, fatty ethers and fatty carbonates, which have a total of at least 24 carbon atoms, specifically laurone and distearyl ether; fatty acids, such as stearic acid, hydroxystearic acid or behenic acid, ring-opening products of olefin epoxides having 12 to 22 carbon atoms with fatty alcohols having 12 to 22 carbon atoms and/or polyols having 2 to 15 carbon atoms and 2 to 10 hydroxyl groups, and mixtures thereof.

Suitable bodying agents are primarily fatty alcohols or hydroxy fatty alcohols having 12 to 22, and preferably 16 to 18, carbon atoms, and also partial glycerides, fatty acids or hydroxy fatty acids. Preference is given to a combination of these substances with alkyl oligoglucosides and/or fatty acid N-methylglucamides of identical chain length and/or polyglycerol poly-12-hydroxystearates. Suitable thickeners are, for example, aerosil grades (hydrophilic silicas), polysaccharides, in particular xanthan gum, guar guar, agar agar, alginates and Tyloses, carboxymethylcellulose and hydroxyethylcellulose, and also relatively high molecular weight polyethylene glycol mono- and diesters of fatty acids, polyacrylates (e.g. Carbopols® and Pemulen grades from Goodrich; Synthalens® from Sigma; Keltrol grades from Kelco; Sepigel grades from Seppic; Salcare grades from Allied Colloids), polyacrylamides, polymers, polyvinyl alcohol and polyvinylpyrrolidone, surfactants, for example ethoxylated fatty acid glycerides, esters of fatty acids with polyols for example pentaerythritol or trimethylolpropane, fatty alcohol ethoxylates having a narrowed homolog distribution or alkyl oligoglucosides, and electrolytes such as sodium chloride and ammonium chloride.

Superfatting agents which can be used are for example lanolin and lecithin, and polyethoxylated or acylated lanolin and lecithin derivatives, polyol fatty acid esters, monoglycerides and fatty acid alkanolamides, the latter also serving as foam stabilizers.

Stabilizers which can be used are metal salts of fatty acids, for example magnesium, aluminium and/or zinc stearate or ricinoleate.

Also suitable are simethicones, which are mixtures of dimethicones having an average chain length of from 200 to 300 dimethylsiloxane units and hydrogenated silicates.

Deodorants and antimicrobial agents that can be used are described in the following text. Cosmetic deodorants counteract, mask or remove body odors. Body odors arise as a result of the effect of skin bacteria on apocrine perspiration, with the formation of degradation products which have an unpleasant odor. Accordingly, deodorants comprise active ingredients which act as antimicrobial agents, enzyme inhibitors, odor absorbers or odor masking agents. Suitable antimicrobial agents are, in principle, all substances effective against gram-positive bacteria, for example 4-hydroxybenzoic acid and its salts and esters, N-(4-chlorophenyl)-N′-(3,4-dichloro-phenyl)urea, 2,4,4′-trichloro-2′-hydroxydiphenyl ether (triclosan), 4-chloro-3,5-dimethylphenol, 2,2′-methylenebis(6-bromo-4-chlorophenol), 3-methyl-4-(1-methyl-ethyl)phenol, 2-benzyl-4-chlorophenol, 3-(4-chlorophenoxy)-1,2-propanediol, 3-iodo-2-propynyl butylcarbamate, chlorohexidine, 3,4,4′-trichlorocarbanilide (TTC), antibacterial fragrances, thymol, thyme oil, eugenol, oil of cloves, menthol, mint oil, famesol, phenoxyethanol, glycerol monocaprate, glycerol monocaprylate, glycerol monolaurate (GML), diglycerol monocaprate (DMC), salicylic acid N-alkylamides, for example n-octylsalicylamide or n-decylsalicylamide.

Suitable enzyme inhibitors are, for example, esterase inhibitors. These are preferably trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and, in particular, triethyl citrate (Hydagen® CAT). The substances inhibit enzyme activity, thereby reducing the formation of odor. Other substances which are suitable esterase inhibitors are sterol sulfates or phosphates, for example lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and esters thereof, for example glutaric acid, monoethyl glutarate, diethyl glutarate, adipic acid, monoethyl adipate, diethyl adipate, malonic acid and diethyl malonate, hydroxycarboxylic acids and esters thereof, for example citric acid, malic acid, tartaric acid or diethyl tartrate, and zinc glycinate.

Suitable odor absorbers are substances which are able to absorb and largely retain odor-forming compounds. They lower the partial pressure of the individual components, thus also reducing their rate of diffusion. It is important that in this process perfumes must remain unimpaired. Odor absorbers are not effective against bacteria. They comprise, for example, as main constituent, a complex zinc salt of ricinoleic acid or specific, largely odor-neutral fragrances which are known to the person skilled in the art as “fixatives”, for example extracts of labdanum or styrax or certain abietic acid derivatives. The odor masking agents are fragrances or perfume oils, which, in addition to their function as odor masking agents, give the deodorants their respective fragrance note. Perfume oils which may be mentioned are, for example, mixtures of natural and synthetic fragrances. Natural fragrances are extracts from flowers, stems and leaves, fruits, fruit peels, roots, woods, herbs and grasses, needles and branches, and resins and balsams. Also suitable are animal raw materials, for example civet and castoreum. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol and hydro-carbon type. Fragrance compounds of the ester type are, for example, benzyl acetate, p-tert-butylcyclohexyl acetate, linalyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, allyl cyclohexylpropionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ether, and the aldehydes include, for example, the linear alkanals having 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, the ketones include, for example, the ionones and methyl cedryl ketone, the alcohols include anethole, citronellol, eugenol, isoeugenol, geraniol, linalool, phenylethyl alcohol and terpineol, and the hydrocarbons include mainly the terpenes and balsams. Preference is, however, given to using mixtures of different fragrances which together produce a pleasing fragrance note. Ethereal oils of relatively low volatility, which are mostly used as aroma components, are also suitable as perfume oils, e.g. sage oil, camomile oil, oil of cloves, melissa oil, mint oil, cinnamon leaf oil, linden flower oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil, labdanum oil and lavandin oil. Preference is given to using bergamot oil, dihydromyrcenol, lilial, lyral, citronellol, phenylethyl alcohol, α-hexylcinnamaldehyde, geraniol, benzylacetone, cyclamen aldehyde, linalool, boisambrene forte, ambroxan, indole, hedione, sandelice, lemon oil, mandarin oil, orange oil, allyl amyl glycolate, cyclovertal, lavandin oil, clary sage oil, β-damascone, geranium oil bourbon, cyclohexyl salicylate, Vertofix coeur, iso-E-super, Fixolide NP, evemyl, iraldein gamma, phenylacetic acid, geranyl acetate, benzyl acetate, rose oxide, romilat, irotyl and floramat alone or in mixtures.

Antiperspirants reduce the formation of perspiration by influencing the activity of the eccrine sweat glands, thus counteracting underarm wetness and body odor. Aqueous or anhydrous formulations of antiperspirants typically comprise one or more of the following ingredients: astringent active ingredients, oil components, nonionic emulsifiers, coemulsifiers, bodying agents, auxiliaries, for example thickeners or complexing agents, and/or nonaqueous solvents, for example ethanol, propylene glycol and/or glycerol.

Suitable astringent antiperspirant active ingredients are primarily salts of aluminum, zirconium or of zinc. Such suitable antihydrotic active ingredients are, for example, aluminum chloride, aluminum chlorohydrate, aluminum dichlorohydrate, aluminum sesquichlorohydrate and complex compounds thereof, e.g. with 1,2-propylene glycol, aluminum hydroxyallantoinate, aluminum chloride tartrate, aluminum zirconium trichlorohydrate, aluminum zirconium tetrachlorohydrate, aluminum zirconium pentachlorohydrate and complex compounds thereof, e.g. with amino acids, such as glycine. In addition, customary oil-soluble and water-soluble auxiliaries may be present in antiperspirants in relatively small amounts. Such oil-soluble auxiliaries may, for example, be anti-inflammatory, skin-protective or perfumed ethereal oils, synthetic skin-protective active ingredients and/or oil-soluble perfume oils.

Customary water-soluble additives are, for example, preservatives, water-soluble fragrances, pH regulators, e.g. buffer mixtures, water-soluble thickeners, e.g. water-soluble natural or synthetic polymers, for example xanthan gum, hydroxyethylcellulose, polyvinylpyrrolidone or high molecular weight polyethylene oxides.

To improve the flow behavior, hydrotropes, for example ethanol, isopropyl alcohol, or polyols, can be used. Polyols which are suitable here preferably have 2 to 15 carbon atoms and at least two hydroxyl groups. The polyols can also contain further functional groups, in particular amino groups, or be modified with nitrogen. Typical examples are:

Also suitable are animal raw materials, for example civet and castoreum. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethylmethylphenyl glycinate, allyl cyclohexylpropionate, styrallyl propionate and benzyl salicylate.

EXAMPLES Collection of Plant Material

Schinus terebinthifolia Raddi, Anacardiaceae leaves, stems, and fruits were collected in bulk from private lands in DeSoto County, Fla. in November of 2013 and 2014 after obtaining permission from the land owner. Procedures from the 2003 WHO Guidelines for good agricultural and collection practices (GACP) for medicinal plants were followed for the collection and identification of bulk and voucher specimens, specifically excluding any populations that may have prior exposure to herbicides. Vouchers were deposited at the Emory University Herbarium (GEO) (Voucher CQ-400, GEO Accession No. 020063) and were identified using the standard Flora for Florida. Plant leaves, stems, and fruits were separated and manually cleaned of soil and contaminants. Plant material was then dried in a desiccating cabinet at low heat. Once dry, plant material was sealed in paper bags and stored at room temperature until further processing.

Extraction and Separation.

Crude methanol extracts of fruits were created by blending a ratio of 1 g dry material:10 mL MeOH into a slurry in a Waring commercial blender for 5 min, and sonicating the material for 20 minutes. Following decantation of the extract, plant material was subjected to two more rounds of sonication followed by filtration. Filtered extracts were combined, concentrated at reduced pressure with rotary evaporators (<40° C.), and lyophilized. The dried extract was resuspended in 1:5 MeOH:H₂O at 1 g:31 mL and underwent sequential liquid-liquid partitioning three times each with an equal volume of hexane, EtOAc, and H₂O saturated n-butanol. The organic partitions were dried over Na₂SO₄ and filtered. Each partition was concentrated in vacuo at <40° C. The hexane partition was dissolved and transferred to a tared scintillation vial and dried under forced air to yield 430B. The remaining partitions were suspended in dH2O, shell frozen, lyophilized and stored at −20° C. The EtOAc partition was labeled 430C, the n-butanol 430D, and final remaining aqueous partition 430E.

Fractionation by Flash Chromatography.

Following initial quorum quenching assays, the most active partition, 430D was subjected to fractionation through flash chromatography. Fractionation was performed using a CombiFlash® Rf+ (Teledyne ISCO) flash chromatography system with a RediSep Rf Gold silica column. The dry load column was prepared by binding extract 430D to Celite 545 at a ratio of 1:4. Flash chromatography was performed using a three solvent system of (A) hexane, (B) dichloromethane, and (C) methanol. The gradient began with 100% A for 6 column volumes (CV), then went to 100% B over 12 CV and was held for 18.2 CV. The gradient was then changed to 74.5:25.5 B:C over the course of 3.1 CV. These conditions were held for 6.8 CV, following which the gradient changed to 68.8:31.2 B:C over 0.7 CV and was held at these conditions for 7.5 CV. Finally the gradient was adjusted to 100% over 2.2 CV and held for 14.6 CV. The chromatography was monitored at 254 and 280 nm, as well as via ELSD. Tube volumes were combined to create eight fractions: 430D-F1 (tubes 1-5), 430D-F2 (tubes 6-11), 430D-F3 (tubes 12-16), 430D-F4 (tubes 17-24), 430D-F5 (tube 24), 430D-F6 (tubes 25-28), 430D-F7 (tubes 29-31), 430D-F8 (tubes 32-38).

HPLC Characterization of Extracts.

Extracts 430, 430D, and 430D-F5 were characterized by high performance liquid chromatography (HPLC). An Agilent Eclipse XDB-C18 4.6×250 mm, 5-μm analytical column, with a compatible guard column, was used at 40° C. Active sub-fractions were dissolved in DMSO (10 mg mL-1), filtered at 0.2-microns, and a 10 μL injection was eluted at a flow rate of 1.9 mL min-1 using a gradient system consisting of (A) 0.1% formic acid in H₂O; (B) 0.1% formic acid in acetonitrile (ACN). The mobile phase was 98:2 A:B at time 0 min, 70:30 A:B at 40 min, 2:98 A:B at 63 min, followed by a hold at 2:98 A:B for 5 min, and ending with a column flush at initial conditions for 5 min. The chromatography was monitored at 217, 254, 320, and 500 nm.

Characterization of 430D-F5 by LC-FTMS.

Liquid chromatography-Fourier transform mass spectrometry (LC-FTMS) was performed on bioactive fractions using a Thermo Scientific LTQ-FT Ultra MS equipped with a Shimadzu SIL-ACHT and Dionex 3600SD HPLC pump. For chromatography an Agilent Eclipse XDB-C18 4.6×250 mm, 5 μm analytical column, with guard column, was used at room temperature. Samples were prepared as previously described and a 50 μL injection was eluted at a flow rate of 1.9 mL min-1 using mobile phases of (A) 0.1% formic acid in H₂O; (B) 0.1% formic acid in ACN. The linear gradient had initial conditions of 95:5 A:B at 0 min and held until 3 min, 68:32 A:B at 23 min, 40:55 A:B at 40 min, 0:100 A:B at 75 min and held for 9 min before returning to initial conditions for a 9 min flush. Data was acquired in MS1 mode scanning from a m/z of 150-1500 in negative and positive ESI (electrospray ionization) mode and processed with Thermo Scientific Xcalibur 2.2 SP1.48 (San Jose, Calif.). The capillary temperature was 275.0° C., sheath gas of 40, source voltage 5.00 kV, source current 100.0 μA, and the capillary voltage −19.0 V or +32.0 V for negative and positive modes, respectively.

Putative formulas were determined by performing isotope abundance analysis on the high-resolution mass spectral data with Xcaliber software and reporting the best fitting empirical formula. Database searches were performed using the Dictionary of Natural Products (Taylor & Francis Group) and Scifinder (American Chemical Society). The databases were reviewed for compounds identified from the genus Schinus with molecular masses corresponding to the LC-FTMS data. Any matches were investigated by comparing the literature and the experimental data; putative compound assignments were made when matches were identified.

Extract 430D-F5 Quenches Quorum Sensing and Toxin Production.

To refine the most active fraction and identify chemical entity inhibitors of S. aureus quorum sensing, a bioassay-guided fractionation strategy was employed (FIG. 2A) using agr-fluorescent reporter stains that represent each of the four known agr allelic groups. Strains were grown in the presence of extracts and monitored for growth inhibition by optical density and agr activity by fluorescence. Extract 430D-F5 inhibited agr at sub-inhibitory concentrations for growth in agr I-IV (FIGS. 3A and 3B). An upper limit of 512 μg mL⁻¹ was used in growth inhibition assays. An upper limit of 128 μg mL⁻¹ was used for detecting anti-agr activity, and IC₅₀ values were 2, 4, 4, and 32 μg mL⁻¹ for agr I-IV, respectively. An IC₉₀ value could only be detected for agr III and was found to be 128 μg mL⁻¹.

To further confirm the quorum-quenching effects of 430D-F5, a number of in vitro tests were pursued to assess its impact on the translational products of agr. Levels of δ-toxin, a phenol soluble modulin responsible for various pathophysiologic effects including cytolysis of red blood cells, neutrophils and triggering inflammatory responses were quantified by RP-HPLC of the bacterial supernatant following treatment with 430D-F5 at sub-inhibitory concentrations for growth effects. 430D-F5 was significantly effective in reducing δ-toxin production in S. epidermidis and in six out of eight S. aureus strains examined (FIG. 4A).

Levels of hemolytic α-hemolysin were also assessed via Western blot following co-incubation with 430D-F5 and similarly demonstrated a dose-dependent reduction. Likewise, hemolytic activity declined with 430D-F5 treatment.

Lastly, to assess any remaining virulence factors linked to cytotoxicity (e.g., phenol soluble modulins), sterile filtered supernatants of NRS385 cultures (a virulent USA500 isolate) grown with 430D-F5 were exposed to an immortalized line of human keratinocytes and assessed for damage by LDH assay and fluorescent microscopy. HaCaTs were protected from damage by supernatants treated at concentrations as low as 10 μg mL-1, and this was confirmed by fluorescent microscopy and LDH assay (FIG. 5).

430D-F5 Shows Limited Potential for Impact on Skin Microbiome.

To determine its potential of for disrupting the skin microbiome and possibly causing dysbiosis, 430D-F5 was examined for growth inhibitory effects against a panel of common nine skin commensals. With the exception of Propionibacterium acnes (MICso of 16 μg mL⁻¹), commensal growth was unaffected at the concentration range necessary for agr-inhibition in S. aureus (IC₅₀ of 2-32 μg mL⁻¹), suggesting that disruption of the skin microbiome would be unlikely.

430D-F5 Impacts Biofilm Formation.

Assessment of the impact of 430D-F5 on biofilm formation revealed a slight significant increase in biofilm production at concentrations ranging from 2-16 μg mL⁻¹, but a notable switch in significant reduction of biofilm formation occurred at higher concentrations tested (32-256 mL⁻¹), also accompanied by a significant increase in planktonic cells at the highest concentrations tested (128-256 μg mL⁻¹) (FIG. 6).

430D-F5 is well tolerated by human cells and mouse skin. To determine its potential for toxicity to human cells, the refined fraction (430D-F5) was tested against an immortalized line of human keratinocytes (HaCaT) cells using an LDH assay for cytotoxicity. The IC50 was determined to be 128 μg mL⁻¹, which yields an initial therapeutic index (TI) of 64 for agr I, 32 for agr II and III, and 4 for agr IV. Furthermore, when administered intradermally to mouse skin, no skin effects, morbidity or mortality were noted.

430D-F5 Abates Quorum Sensing and Dermonecrosis In Vivo.

The potent inhibitory activity of 430D-F5 upon agr reporter activity in vitro encouraged us to assess the efficacy of the mixture within the context of MRSA infection in vivo. Using a cutaneous challenge mouse model of USA300 MRSA27, a single dose of 430D-F5 delivered at the time of infection was found to attenuate skin ulcer formation in a dose-dependent manner (FIG. 7A). In addition, 430D-F5 treated animals exhibited significantly less infection-induced morbidity, as assessed by weight loss when compared to vehicle treated controls.

While 430D-F5 mixture clearly attenuated MRSA disease pathology, whether quorum-sensing was inhibited during the course of infection was unclear. To address this question, a MRSA agr P3-lux reporter was tested that could track agr function in real time. Following infectious challenge, the attenuation of MRSA virulence in 430D-F5 treated animals occurred alongside significant suppression of agr activity in vivo (FIG. 7C). Together these data demonstrate that the 430D-F5 mediated attenuation of MRSA pathogenesis corresponds with potent quorum quenching activity both in vitro and in vivo.

Chemical Characterization of 430D-F5.

LC-FTMS analysis of 430D-F5 yielded 27 peaks (FIG. 8A) with exact masses reported in FIGS. 8B, 8C, and 8D. Notably, the 430D-F5 fraction is rich in flavones and steroidal sapogenins (FIG. 8E), exhibiting a different chemical profile than that recently identified in a similar analysis of the quorum quenching activity of a chestnut leaf extract, which was rich in oleanene and ursene derivatives reported in Quave et al. Castanea sativa (European Chestnut) leaf extracts rich in ursene and oleanene derivatives block Staphylococcus aureus virulence and pathogenesis without detectable resistance. PLoS ONE 10, e0136486, (2015). Peaks 2 and 4 correspond to flavones, representing nearly 34% of the relative abundance in negative ESI mode. Their higher ionization in negative over positive ESI mode supports the conclusion that these are highly hydroxylated flavone skeletons. The steroidal sapogenins correspond to peaks 14 and 19, with 5.3% and 1.0% relative abundance respectively. Their lower abundance could also be due to poor ionization in both positive and negative ESI modes.
